Pd/IG composite, a new class of heterogeneous collagen peptides–metal BNCs that exhibit high catalytic activity and reusability for ligand-free Suzuki coupling reaction in water. Additionally, these BNCs are obviously active in the cross-coupling reaction between acid chloride and arylboronic acid, producing a high yield of the desired ketones. The synthesized BNCs are well-characterized by Fourier
生物纳米催化剂(BNC)是一项不断发展的创新,可以将先进的纳米技术与生物技术协同作用。BNC由于其化学药品的低消耗量和无毒副产物的存在而促进了绿色过程。Isinglass(IG),来自荷兰huizenblaas(st鱼膀胱)含有约98%的蛋白质胶原蛋白,用于支持钯(Pd)纳米粒子的固定化。这一过程导致了Pd / IG复合材料的出现,这是一类新型的异质胶原肽-金属BNC,对水中的无配体Suzuki偶联反应具有很高的催化活性和可重复使用性。另外,这些BNC显然在酰氯和芳基硼酸之间的交叉偶联反应中具有活性,从而产生了高产率的所需酮。通过傅立叶变换红外光谱,场发射扫描电子显微镜,X射线粉末衍射,X射线光电子能谱,能量色散X射线能谱,电感耦合等离子体和透射电子显微镜,可以很好地表征合成的BNC。
